LINE-CASTING Mnonmn.

Specification of Letters Patent.

Application filed December 4, 1908. Serial No. 465,929.

Patented June 8, 1909.

To all whom it may concern:

Be it known that I, Jon's R. ltoenns, of borough of Brooklyn, county of Kings, and State of New York, have invented anew and useful Improvement in Line-Casting Mn chines, of which thcl'ollowing is a .-'-y r-.ifi -ai tion. V

This invention is intended. more pin-lien larly as an improvement on the line ca ting machine represented in Letters Patent ol' the United States to J. R. l'iogers #679481.

In machines of this class, a composed line of matrices, sus ended from parallel guide wires, is pushed 'orward by a-finger from the composing position to the casting'position in front of the mold, all the parts being driven through a friction clutch which slips in the event of its meeting excessive resistance.

The carrying finger is attached to an endless power driven chain, and in practice it occasionally happens that the momentum of the parts is such that they carry the linger and the matrix line beyond the proper posi-v tion at the casting point.

The object of the present invention is to effect a positive stoppage oi" the line at the proper point, and to this end it consists in a mechanically actuated stop, arranged to arrest the line carrying finger at the proper point.

With the exception of he parts hereinrespects ol' the ordinary construction.

Figure 1 is a perspective view showing a composed line of matrices at the casting position, together with the adjacent parts oi the machine, having my ll'IlPI'OVOHlOIli) embodied. therein. Fig. 2 is a cross section. on the line 22, Fig. 1.

Referring to the drawings, A represents the inclined guide wires i'roi'n. which the matrices Z are suspended.

J represents the finger by which the composed line of matrices is carried forward from the composing position to the casting position, as shown in Fig. 1. This finger is attached to and depends l'rom an endless carrying chain L, suitably guided and, driven by mechanism so arranged that when the finger has advanced the matrices to the casting position the driving devices are automatreally disengaged, so that the chain and finger may stop.

All of the foregoing parts may be constructed and arranged to operate as in Patent 679,481, the parts indicated by-like letters correspomling to those herein; the

, onnection'of the finger with the chain being preferably such as shown in Letters Patent Trance.

In pracl ice the momentum of the carrying chain. the linger, and the matrix line is such that the line is occasionally carried beyond the proper casting position, and it is to overcome this difficulty that my invention is intended.

S represents a rigid arm on the top of and forming a part of the movable metal pot, which swings, as usual, toward and from the matrices and against the intervening mold, the mold being omitted from the present drawings in order to expose the other parts to view. A

In applying my improvement, l provide an automatically actuated. stop, by which the advance of the chain and carrying finger J is arrested as soon as the finger has advanced the line of matrices Z to the casting position. This stop may be made in various forms, and operated from any suitable moving part 01' the machine, but lv recommend the arrangement shown in the drawing in which C represents a stepping finger pivoted at c to the top frame of the machine and bent laterally at the upper end, that it may be projected in front of the block which connccts the finger J with the carrying chain 11 in the manner indicated in Figs. 1 and 2, so that it will positively arrest the chain and finger and ])I'OV(JIt1tlIOII1 from carrying the matrices beyond-the proper position. The finger (J is pivoted to and actuated by a horizontal bai'D, resting on top of the pot arm S, and provided with downwardly projecting sl'ioulders, d and d, so located that as the pot swings to and fro it will move the bar 1) and actuate the stop C. The parts are so proportiomxd and arranged that the backward movement ol' the pot withdraws the stop (3 in time to permit the proper advance of the chain and finger alter the casting operation, when the matrix line is to be.advane-ed rearward for distribution. is thrown forward to an operative position before the line maches the casting position, and in time to arrest the chain and finger before the matrix line is overcarried.

The stop The bar D may be provided with screws, 05 and (i to contact with the pot. The adjustment of these screws will permit the movement-of the stop C to be controlled with great nicety.

' Having thus described my invention, what I claim is:

1. In amachine of the class described, in combination, pendent matrices, and guides whereon they travel to and beyond the casting position, means for advancing the line to the casting position, and automatic means for positively arresting the advancing lines and ,preventing the line from being overearried through momentum.

2. In a machine of the class described, a

chain and finger for advancing the matrix line to the casting position, in combination i with an automatically actuated stop to arrest the finger when the line is in the casting position. i

3. In a machine of the class described, the l guides, matrices suspended therefrom, and the power driven finger to advance the matrix line to the casting position, in eom- E bination with a movable stop to positively arrest the finger at the casting point.

4. Ina line casting machine, a movable pot, a mold, and means for presenting a centposed line of matrices to the mold, in cembination with means controlled by the pot to control the travel of the line and insure its location in the proper casting position 5. In combination, the inatrixcarrying finger and chain, and stop 0 to limit the ad Vance of the finger, movable pot S, and means through which the pot controls the stop. v

6. In a machine of the class described, the

matrix carrying finger, the swinging pot, and 1 means controlled by the pot to arrest and release the finger.

In testimony whereof I hereunto set my hand this twenty seventh day of November,

1908, in the presence of two attesting witnesses.
